Come later this week, watch out!!!
One of the things that will happen with that shift is a great number of larger pieces of float-sum that WAS up high on the bank will get sucked out into the current with the falling water. Lots of this stuff has been sitting high and dry for a while and will float where you can see it. Of more concern is the stuff that is a bit more waterlogged and therefor will be floating just barely at the surface, of below a tiny bit.
Could be worse than normal as there is still a pile of pilings and boards and sections of dock left from Irma that will move.
